Countess Mathilde of Boulogne

Biography
Countess Mathilde of Boulogne was born on 2 January 1105 to the House of Boulogne, a dynasty of French Catholics. She was the daughter of Count Eustache III of Boulogne and Mary Dunkeld, coming from the House of Boulogne (ruling the County of Boulogne) and the House of Dunkeld (ruling the Kingdom of Scotland). She was the only heiress to Eustache III, and she married Stephen of Blois, the ruler of the County of Blois in Normandy. In 1135 she became the King of England after Stephen of Blois was chosen by the people of London to succeed Henry I of England, and her husband would ironically campaign against her when he besieged Boulogne during his campaigns against the Kingdom of France. Her domains were seized by the English, and she became a vassal of her husband.
